摘　　要：裂缝型油气藏油气产量占整个石油天然气产量的一半以上 ,是 2 1世纪石油增储上产的重要领域之一 ,但目前致密储集体裂缝参数的定量表征和空间分布规律定量预测评价 ,仍是石油地质界的前沿问题 ,在一定程度上阻碍了世界石油工业的发展。从国内、外研究现状来看 ,对裂缝及裂缝型油气藏预测评价研究仍处于探索阶段。世界上大多数裂缝性油气田的裂缝主要为构造裂缝 ,对构造裂缝空间分布规律的合理预测评价 ,无疑对油气勘探开发起到科学的指导作用。本文综述了储层裂缝研究现状、进展和主要研究方法 。More than half of oil gas gross output in the world comes from the fractural oil gas pools, which will constitute one of the most important oil-gas producing fields in the 21st century. Nevertheless, the complexity of fractural reservoirs in petroliferous basins has hindered the development of petroleum industry.Viewed from the research situation both in China and abroad, the quantitative prediction of spatial distribution of compact and fractural reservoirs, the quantitative depiction of reservoir fracture parameters and the quantitative evaluation of such reservoirs remain the forefront problems in petroleum geology which require further deepgoing investigation. This paper summarizes the research situation,major progress and methods of quantitative prediction and evaluation of the natural fracture system of reservoirs. At the same time,some examples are given for illustrating the role of quantitative prediction of reservoir tectonic fractures in the exploration of oil gas resources.It is hoped that such work will enlighten petroleum researchers on this subject.
